Smartphone jammer

1 Name: Anonymous 2020-04-20 12:41
Hey guys

I was wondering if there is a device to jam smartphone frequencies available to buy. I don't need it to affect the phone, i just need to block the connection. Ideally it will be portable or 12v and with a range of at least 30m. I need it to work 100% of the cases, even through a few walls.

Does anyone know a device? Or how to build it?

Yes, there are such devices, but they are illegal, and having one with you would land you some serious trouble.
It's a pretty simple device: it just needs to spam noise in a couple frequencies.
What do you need it for?
If you consider the risk worth it (and it's a pretty big risk! they are detected as soon as you turn them up...), probably the best way of getting one would be buying any software-defined-radio device, and doing some coding.

You are an idiot.

Santa is also from Brazil and the Easter Bunny is actually an armadillo
